Hi Dave, im going to try to do a plugin in order to have a "Friends Only" access level.

Any advices?

Hello, i have coded a little trick in order to have a "Friends Only" access level, i have tested it on my elgg 1.1 with blog plugin and it seems to work correctly.

In /engine/lib/access.php:

Line 165:

//if (empty($sql))
                    //$sql = " ({$table_prefix}access_id in {$access} or ({$table_prefix}access_id = 0 and {$table_prefix}owner_guid = $owner))";
                //HACK
                global $CONFIG;
                if (empty($sql))
                    $sql = " ({$table_prefix}access_id in {$access} or {$table_prefix}owner_guid = $owner or ({$table_prefix}access_id = -1 and {$table_prefix}owner_guid in (select guid_one from {$CONFIG->dbprefix}entity_relationships where guid_two = $owner and relationship = 'friend')))";

Line 200:

//$tmp_access_array = array(0 => elgg_echo("PRIVATE"), 1 => elgg_echo("LOGGED_IN"), 2 => elgg_echo("PUBLIC"));
                //HACK
                $tmp_access_array = array(0 => elgg_echo("PRIVATE"), 1 => elgg_echo("LOGGED_IN"), 2 => elgg_echo("PUBLIC"), -1 => elgg_echo("FRIENDS"));

Line 439:

//HACK
        define('ACCESS_FRIENDS',-1);

I hope this is okay :)

Regards!

I forgot it! The code is based on http://trac.elgg.org/elgg/ticket/74 ;)
